Application filed. October 2, 192a. serial n 66 ,166.

To all whom it may concern. y

Be it known that we, Austrian E. HUGHES, RALPH K. Nn'w'roN, and RUFUS T. Nnw'ron, citizens of the United States, residing at Graham, in the county of Tazewell and State of Virginia, have invented a new and useful Camera Attachment, of whichthe following is a specification. I

The device forming the subject matter of this application is an attachment "for a camera, and this invention aims to provide novel means whereby, after an'exposurehas been made, a predetermined amount of film will be wound away automatically, and a new portion of the film being moved into the field of the lens of the camera,

It is within the prfovince of the disclosure to improve generally and to enhance the utility of devices of that type'to which the invention appertains.

lVith the above and other objects in view, which will appear asthe description proc'e'eds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it b'eing understood that, within the scope of what is claimed, changes in the precise en'ibodiment of the invention shown, can be made, without departingfroin the spirit of the invention, I v v In the accompanyingdrawings 5- Figure 1 shows in side elevation, a. camera equipped with the device formingthe subject matter of this application, parts being broken away; Figure 2 is a front elevation wherein parts are broken away; Figure 3 is a section taken through a portion of the winding mechanism; Figure 4 is a view similar to Figure 1, but showing parts in a different position from that depicted in Figure 1; Figure 5 is a top plan wherein parts are broken away; Figure 6- is a; rear elevation, parts appearing'in section; Figure 7 is a side elevation whereinparts are broken away.

The numeral l marks the casing of a camera, the numeral 2 designating the usual hinged table, adapted to be swung downwardly to a horizontal position, as shown'ih Figure 1. The bellows appear at 3 and is connecte'dto a top member 4, slidable on the table, f l -all as usual. The shutter lever is marked by the numeral 5.

In carrying out the invention, an operating lever 6 is mounted to swing on the/front lever with the shutter lever 5.

At -it's lower end, the plunger lO'is supplied with 'a finger 17 engaged with an arm 18 rock shaft 19 j'ournaled in bearings 20 on the table 2, the shaft being oiiseta's-at fl clear the tripod lug 22' on the table 2. At its in nor end, the rock shaft ioii previded with a crank'arin Q-B located above a projection 24 on the offset foot 25 of a plunger '26, the foot 25 being mounted to slide iiia guide 27 on the casing 1. At its upper" end, the plunger 26 has a head 28 slidabl'e ina ide 29 on'the c'asingl. The piungereesii e's iii an abutment 30 on thecasing 1'. Aeom'pression spring 81 surrounds a portion oftlre plunger 26, one-end ofthe spring engaging the abutment 30, and the other eiidb-f the spring engaging the head 28 of the plunger. Thefunction of the springiiiis' to elevate the plunger 26 into the position showni'n Figure 1. The plunger 26'andfparts hereinbcfore and hereinafter described are located within ahousing32connected to'tlie in'ain casing 1 of the camera. I i A supplemental casing33 is mounted on the casing 1; Awinding shaft 34 isjournaled in the casing SBand is adapted to be actuated by a removable key 35 toput tension spring 36 connected to a driving gear 37 journaletl' on the casing 1, the driving gear 37 meshing with a'driven pinion38 ona stub shaft 39 in: the casing 1, the shaft 39 carrying one of the spools or reels 7 5 for the film. A shaft 40 is journaled in the casing land in apart of the casing 33; The shaft '40 carries a gear wheel 41,1n'e'shiug with the driven pinion 38. ,A combined escape and stop wheel 42 is'securedto the shaft 40-. The

escape wheel 42cooperates with a pallet 43" on a shaft 44 carrying a combined escape the shaft 44, on the camera. v

The escape and stop lever 45 hassliding movement beneath a 'bracket'46. A lower end of the escape lever 45 extends into the path of the head 280i the plunger 26, the

parts 28'a nd 45 being rounded for engage ment with eachothe'r, as indicated by thenumovement towards ineral 47. The lever .45 oscillates betweena fixed stop 48 on the casing 1, and a stop 49,

"adj'ustably secured at 50 to the casing for and away from the stop 4 V A keeper51 is formed in the head 28 of the plunger 26 and is adapted to cooperate with' a latch 52' slidably'in a holder 53 on the casing 1, the latchhaving adepending finger 5'4, against which bears a leafspring 55,

serving "to advance the latch," the lower end of the spring 55being secured to a'guide 56 on the casing 1. A bell crank lever 57 is 'fulcrumed at 58 on the casing 1, the upper end of the bell crank-lever cooperating with the depending projection 54 on the latch 52.

'A' pitman 59 is adapted to cooperate with the lower end ofthe bell crank lever 57 and is mounted for swinging and for longitudinal movement in the guide 56. man 59 is pivoted, at 60 to a; gear wheel 61, jo'urnaled at 62 on the casing of the gear wheel 61 meshing with a pinion 63 on a shaft 64 journaled in'elonga'ted slots 65 formed in bearings 66 on'the casing 1, theshaft being provided with a roller 67 having a circumferential :groove 68 whereln 1s received a spring tongue 69 secured to the casing 1, the

tongue69 and theroller '67 7 being located within an offset covering 7 0 on the casing 1. The reel which carries one end of the film 72 is designated by the numeral 71, thefilm traversing a'guide73 in the casingL the spring tongue 69serving to press the roller 67 against the film' 72, as the film traverses a fixed 1 portion" 74' of the camera, as delineated in Figure 4 o fthe drawings.

In'practical operation, the lever 6 is swung downwardly, and the cross piece 8 on the lever, cooperating with the shutter lever 5, causes the shutter to make the desired exposure. When theoperating 'lever 6 swings downwardly, the cross piece 8 on the operating lever moves along the beveled1edge'16 ofthe'plunger 10 and engages'the shoulder 15 on the plunger. Then the lever 6 swings upwardly responsive to the action of "the spring 7, the plunger 10 is elevated, the cross piece 8 of theoperating lever ultimately sliding from the shoulder 15, and-permitting the plunger 10 to move downwardly under the actionzof the spring 31, the action of the The pit-- spring being moreclearly manifested as the description of the operation of the device proceeds. V

, Revertlngito the upward movementofthe Iplunger lO, under the actionof the lever 6, p the finger 17 on the lowerend of the plunger 7 10, cooperating with the arm 18 on the shaft 19, rocks'the shaft. Whenthe shaft 19 is rocked, the crank-arm 23 onthe shaft, coa'cting with the projection 24 on the foot 25 of the plunger 26, draws the plunger 26, downwardly, the spring 31 being compressed. WVhen the plunger 26 is drawn downwardly,

the head 28 of the plunger is moved out of the path of the lower end of the lever 45, and

the lever 45,"together with the pallet 43, are

setfree for swinging movement. Thelever 45 and the pallet 43 swing, responsive to the action of escape wheel 42, rotation being imparted to the escape wheel on thespring '36,

by way ofj-the driving gear 37,- the. driven pinion 38, the gear wheel41 and' the shaft 40 Whenthe shaft ,39 is rotated through I lever 57 and the bell crank lever 57 swings on its fulcrum 58, thereby setting free the latch 52, the latch 52advancing under the I M action'of the spring 55 until the latch 52 95 guide 56 out ofithe pathofythe bell crank I is engagedinto the keeper 51 on the head 28) of the plunger 26, thereby holdin gthe head 28 of" the plunger 'depressed' and out of the ;way of thelower end of the lever 45.' The lever- 45 continues to swing, and the shaft 139 and the spool 7 5 continue to rotate underthe impulse ofthe spring 36,,until the exposed portion of the film has beenwound outof the way. By this time the gear wheel 61 has been carried into position shown in Fig ure 1 and the pitman59 has tilted'the bell crank lever 57 on its fulcrum 58until the 51in the head 28 of the plunger 26, the plungerv 26 rising under the action-of the spring 31 until the head 28 of the plunger again is.
